ROUND-FRUITED PANIC GRASS
Panicum sphaerocarpon of Michigan Flora.
Dry open sandy ground, fields, and sandy forests.
The leaves, especially those in rosettes, are not only quite large for a plant with such small spikelets, but the leathery rosette leaves have rather contrasting whitish venation that makes them stand out.
At high magnification (30×), the slightly swollen zone of the stem below the nodes, and sometimes elsewhere, the panicle branches, there are characteristic tiny yellowish or whitish elliptic, ± shiny glands diagnostic for this species.
